Constraints on the space density of intermediate polars from the Swift-BAT survey
Constraints on the space density of intermediate polars from the Swift-BAT survey
We construct a complete, hard X-ray flux-limited sample of intermediate polars (IPs) from the Swift-BAT 70-month survey, by imposing selection cuts in flux and Galactic latitude (FX > 2.5 × 10− 11 erg cm− 2 s− 1 at 14–195 keV, and |b| > 5°). We then use it to estimate …
